Registering a Company Under the Thailand Board of Investment

Thailand has emerged as a dynamic hub for business and investment in Southeast Asia, offering a strategic location, skilled workforce, and a conducive business environment. Registering a company under the Thailand Board of Investment (BOI) is a key pathway for businesses looking to benefit from incentives and promote economic growth. This comprehensive guide explores the process of registering a company under the BOI, the incentives available, eligibility criteria, and the impact of BOI promotion on business operations in Thailand.

The Thailand Board of Investment (BOI):

  1. Role and Objectives:

    The BOI is a government agency established to promote foreign and domestic investment in Thailand. Its primary objectives include stimulating economic development, enhancing competitiveness, and attracting strategic investments in priority industries.

  2. Incentives Offered by the BOI:

    Companies registered under the BOI enjoy a range of incentives to foster business growth and development. These incentives may include tax exemptions, import duty reductions or exemptions, and other non-tax privileges.

Eligibility Criteria for BOI Promotion:

  1. Eligible Activities:

    The BOI promotes investments in specific industries and activities categorized into three main groups: Activities A, B, and C. Activities in Group A receive the highest level of incentives, while those in Group C may receive fewer incentives.

  2. Foreign Ownership:

    Foreign-owned businesses are eligible for BOI promotion, but the level of promotion may vary based on the type of business activity. Some activities may have restrictions on the level of foreign ownership, and certain industries may require approval from specific government agencies.

  3. Minimum Investment Requirements:

    The BOI sets minimum investment requirements for each promoted activity. The investment can include expenditures on machinery, construction, and working capital. Meeting the minimum investment threshold is a key criterion for eligibility.

  4. Promotion of Innovation:

    Activities that incorporate advanced technology, research and development, or innovation may receive additional incentives. The BOI encourages businesses to contribute to the development of Thailand’s knowledge-based economy.

The Process of Registering a Company Under the BOI:

  1. Pre-Application Phase:

    Before submitting a formal application, businesses often engage in pre-application consultations with the BOI. This phase allows for discussions on eligibility, incentives, and any specific requirements related to the proposed investment.

  2. Application Submission:

    The formal application involves submitting a comprehensive proposal to the BOI. This proposal should outline the details of the investment, including the nature of the business, the projected investment amount, employment opportunities, and the expected benefits to the Thai economy.

  3. BOI Evaluation:

    The BOI reviews the submitted application, assessing its compliance with eligibility criteria and evaluating the potential impact on the economy. This phase may involve clarifications and additional documentation to support the application.

  4. Approval and Promotion Certificate:

    Upon successful evaluation, the BOI issues an approval letter and a promotion certificate. The promotion certificate specifies the incentives granted to the business, including tax privileges, import duty exemptions, and other non-tax incentives.

  5. Company Registration:

    After receiving BOI approval, the business must proceed with the formal company registration process with the Department of Business Development (DBD) under the Ministry of Commerce. This involves the issuance of a company registration certificate.

  6. Operational Implementation:

    With BOI promotion secured, the company can commence its operations, taking advantage of the approved incentives and contributing to the economic development of Thailand.

Key Incentives Provided by the BOI:

  1. Tax Incentives:
    • Corporate Income Tax Exemption: Businesses may be eligible for full or partial exemption from corporate income tax for a specified period, depending on the promoted activity.
    • Import Duty Exemption: Exemptions or reductions on import duties for machinery, raw materials, and essential inputs are provided to BOI-promoted businesses.
  2. Non-Tax Incentives:
    • Permission for Foreign Employees: BOI-promoted companies are often granted permission to employ foreign nationals in key positions, facilitating the recruitment of specialized talent.
    • Land Ownership: Some BOI-promoted activities may receive permission for foreign-owned businesses to own land in Thailand for operational purposes.
  3. Additional Incentives for Certain Activities:
    • Research and Development (R&D): Businesses engaged in R&D activities may receive additional incentives, such as an additional three-year corporate income tax exemption.
    • Environmental Conservation: Companies incorporating environmentally friendly practices may receive incentives, including corporate income tax exemptions and duty-free importation of pollution control machinery.

Challenges and Considerations:

  1. Compliance Requirements:

    Maintaining compliance with BOI regulations is crucial. Failure to adhere to the stipulated requirements may result in the revocation of incentives or other legal consequences.

  2. Documentation and Reporting:

    BOI-promoted companies are required to submit regular reports to the BOI, detailing their investment progress, employment levels, and other relevant information.

  3. Changing Economic Conditions:

    The BOI may periodically revise its policies and incentives based on changing economic conditions. Businesses should stay informed about any updates or changes that may impact their operations.


Registering a company under the Thailand Board of Investment presents significant opportunities for businesses seeking to establish a strong foothold in the country. The BOI’s role in promoting key industries and offering incentives underscores its commitment to fostering economic growth and attracting strategic investments. By navigating the registration process diligently, adhering to compliance requirements, and leveraging the provided incentives, businesses can contribute to Thailand’s economic development while securing a competitive edge in the region.
